To aZZ whom it may concern:

Be it known that I, GAETANO Lim u, a subject of the Kingof Italy, and aresident of San Jose, in the county of Santa Clara and State ofCalifornia, have invented certain new and useful Improvements inWhirligigs, of -whichthe following is a specification.

My invention relates particularly to a toy comprising a miniatureaeroplane moored to and movable in a circle about a rod or handle.

It is one object of-the invention to provide adevice of the characterindicated in which the revolution of the propeller occasioned by therapid movement of the aero plane through the air operates a noise making mechanism.

It is another object to provide -a device of the character indicated inwhich the sup porting body portion of the aeroplanefunctions also asa'housing. for the propeller shaft and cooperates with the shaft toproduce a noise when the shaft is revolvedf In the drawing.:-

Figure 1 is a plan view of -the device.

Figure 2 is a front elevation of-the same. Figure 3 is anenlarged'longitudinal vertical section through the device.

Figure 4 is an. enlarged front elevation of the propeller Figure 5 is anenlarged perspective view.

of the noise making end of the propeller shaft.

Referring more particularly to the drawing, I show at 1 an aeroplanebody formed in any suitable shape and of any suitable material, andrigidly supported by an open ended tube 2 passing longitudinallytherethrough and elevated at its forward end as shown, the tube beingfunnel shaped in form and arran ed with its larger end ex- A certainportion of the interior surface of the tube is roughened by punching upbosses as shown at 3.

The body 1 is provided with wings or planes 4, tail planes 5 and a tailpiece 5".

The planes 4 are braced by wires 6 extending transversely thereof, and abrace wire 7 extending from one wire 6 through a slot 8 formed in thenose of the aeroplane to the other wire 6 as shown, and thence laterallya distance beyond the aeroplane wing to form a support 9. This wire isresilient and is twisted to form terminal loops at 10 through which theend of a rod 11 is thrust.

'of the wire support 9 about rod 11.

' propeller 15.

The loops 10 are held in position on the end of rod 11 by pins 12 placedabove and below .them so as to permit the free rotation The size andshape of the wire support!) and the degree of its curvature away fromrod 11 are such that when it is completely assembled and the rod 11 heldin a vertical posi tion the wings 4 of. the plane will'lie in asubstantially horizontal position.

At 1.3 I show a rod or propeller shaft having one end fitted with a pairof rectangular plates 14 arranged end to end and in planes intersectingeach other at right angles.

The other end of the shaft 13 carries a i This propeller comprises apair of blades 1616 symmetrically arranged about the shaft 13. The basesof the two blades are joined into one integral whole, the base of onecurving around the central hub portion 17 and merging with the baseportion of the other blade. The two blades are arranged at a suitableangle, andpreferabl taper toward their outer ends as shown. y thisformation of the blades they are effective in their action on the airfrom the very center oint to their tips and consei'plently their eciency is exceptionally hig 1.

With the bod. of the device constructed as described. an pro erlymounted on rod 11, the long shaft 13 is inserted in the nose of theaeroplane through the open larger end of the tube 2, and of course isfreely revoluble therein.

When the device is assembled as set forth, and the rod 11 held in avertical position and given a rating movement, the aeroplane is cause totravel in a circlb about the rod 11. In travelling in this manner theresi'stance of the air causes the propeller to revolve with more or lessspeed, and of course the shaft 13 revolves therewith. In revolving, theshaft 13 causes the rectangular plates 14 to strike the irregularlyraised bosses 3 in tube .2, thereby creating a noise pro ortional tothespeed'of rotation of the sha 13.

The lates 14 are somewhat smaller in sin than tie diameter of thatportion of the tube 2 in which they operate so that they may be thrown.freely about therein.

It is obvious, of course, that while I have herein shown and describedone specific embodiment of my invention, changes may be ice made inform, proportions, construction and method ofoperation, within the scopeof the appended claims.

I claim:

1. A toy comprising an aeroplane body having laterally extending wings,a supv orting element extending from a point adacent the extremity ofone wing diagonally to thenose of said body, thence diagonally to apoint adjacent the extremity of the other wing, and thence laterally ofthe aeroplane body a distance and provided with means for revolubly on avertical support.

2. A toy comprising an aero )lane body having an open ended tube extening lengthwise therethrough, a rod loosely insertable and freelyrevoluble in said tube, and a propeller carried by said rod, said rodcarrying a rattle on the portion within said tube.

3. A toy comprising an aeroplane body having a tube extendingtherethrough, a rod loosely insertable and freely revoluble in saidtube, a propeller mounted on said rod, and noise making mechanisminserted between said rod and tube, a part of said mechanism beingcarried by said tube.

4. A toy comprising an aeroplane body, a tube extending lengthwisetherethrough', a rod loosely insertable in said tube, and a propellermounted on said rod, said tube havmonnting the element ing a roughenedinterior and said rod carrying elements enga cable with said roughenedinterior to ma e a noise when revolved by the rotation of saidpropeller.

5. A toy comprising an aeroplane body, a

tube extending lengthwise therethrough and taperingtoward its forwardend, a prope ler operated rod loosely insertable in said tube and freelyrevoluble therein, and a propeller mounted on said rod, said rodcarrying laterally projecting parts on the end opposite to saidpropeller and within the larger portion of the tapered tube.

6. Atoy comprising an aeroplane body, a tube extending lengthwisetherethrough and inclined downwardly from the nose to the tail portionthereof and tapering toward its forward end, a propeller operated rodloosely insertable in said tube and freely revoluble therein, and apropeller mounted on said rod, said rod carrying laterally projectingparts on'the end opposite to said propeller and within the largerportion of the tapered tube.

7. A toy comprisin an aeroplane body having a tube inserts in itsforward end, a rod loosel inserted in said tube and freely revolubleterein, a propeller carried by said rod, and noise making mechanism in-'serted between said rod and tube.
